Organizations interested in using analytics to predict outcomes will score data pools by applying an appropriate predictive model. Pre-built predictive models are becoming increasingly available in the market place. Data scientists that are knowledge experts in particular areas are developing models that have increasingly better success rates. However the best approach may be for an […]

Lift Analysis and IBM SPSS
Defining what lift is “Lift” is the measure used to determine how well your targeting model does at prophesying cases as having a greater response with respect to the population as a whole.

Generally speaking, an […]
Basic Data Analysis and IBM SPSS
The basic steps in data analysis might be simplified into (1) Identifying data, (2) Selecting an analysis and summarization method and (3) Presenting the results. Over the next couple of weeks I will look at using IBM SPSS version 20 to accomplish these tasks. Today, I want to focus on loading a data […]
Interoperability and PMML
If you work within the rapidly expanding analytics space, you will need to think about defining and sharing statistical models between applications. PMML (or Predictive Model Markup Language) is an XML-based language developed by the Data Mining Group (DMG) for this purpose. I’d like to pass on some of the essentials: The Basics PMML provides […]
